Images: Tsunamis, hurricanes hit 'Second Life'

<br /><p>On Thursday, the U.S. National Oceanic and Atmospheric Administration launched an immersive, interactive 3D presence in the virtual world <i>Second Life</i>.</p>
<br />
The site, created by NOAA's Earth Research Lab, gives <i>Second Life</i> users the opportunity to walk through a series of interactive exhibits, showing, for example, the effects of global warming on large glaciers; what it's like to fly in a NOAA plane or weather balloon into, through or around a hurricane; and what undersea caves and marine life look like from a submarine.

Here, the exhibit showcases the effects of a tsunami, demonstrating first what happens when the water pulls back.

One exhibit in NOAA's virtual island in Second Life showcases what the Earth looks like at night from outer space. It's possible to see lights of cities and developed areas on the planet from space, particularly in the West, where there are many more industrial areas than on other parts of the globe.

On the plane ride available to Second Life visitors to NOAA's island, the flight goes up and through a hurricane, giving a sense of what the storm looks like on the inside. It also shows how the weather around the hurricane includes heavy rain and other rough conditions.

NOAA's Second Life island includes several exhibits showcasing weather-related experiences. Here, users can see a large-scale interactive and real-time map of the United States displaying weather conditions in various parts of the country. It resembles the maps shown on TV news stations' weather forecasts, but allows users to walk or fly into and around it.

Another exhibit on NOAA's Second Life island shows the effects of a glacier on sea levels. In this first image, the glacier is fully formed, and the bridge in the foreground is well above the water line.

In this last of three images taken on NOAA's Second Life interactive island, the glacier exhibit shows that the glacier has fully melted, and that the bridge has been completely submerged by the rising sea.
